Ship building



Nov. 19, 1929. H. K. KLIOESS SHIP BUILDING Filed Sept. 10, 1927 Patented Nov. 19, 1929 UNITED STATES HANS KARL KLOESS, OF HAMBURG, GERMANY SHIP BUILDING Application filed September 10, 1927, Serial No. 218,679, and in Germany May 21, 1927A relation to the central plane of symmetry for the fore and aft sections of the vessel, since these points may occupy a different relative position so as to ive a difl'erent degree of inclination to the rames in the fore and aft sections of the vessel.

On the accompanying drawing I have illustrated the principle of my invention.

In the single figure of the drawing, the

line WAZ denotes the water-line of the ship, while the line XY denotes the central symmetrical plane in the longitudinal directionof the vessel. B is the bottom line of the vessel, while A, A indicate the side walls which as shown in the drawing downwardly extended by the broken lines form with line B and line W-AZ a rectangle. The lines OA and Oo-A represent the main diagonal of the vessel.

From the point 0 outside of the hull and disposed below the bottom line B radiating lines 1 2 3 4 5 6 are generated which lines determine the direction of the frames of he fore section, while from another point O disposed outside the hull below the bottom line B radiating lines 1, 2, 3, 4, 5, 6 are generated which determine the direction of the frames of the aft-section of the-ship.

Point 0 the radiating lines from which point determine the degree of inclination of the frames in the fore-part of the vessel is located at a comparatively large distance from the bottom line B of the vessel, the l cation depending on the ratioof the beam W.-Z to the depth W--() and also the speed for which the vessel is built. I

Point O, the radiating lines from which 5 point determine the degree of inclination of the frames in the aft part of the vessel is located closer to the bottom-line B, and the location of this point likewise depends on the ratio of the beam of the vessel to its depth and the speed.

As clearly shown on the drawing, the frames in the fore part of the vessel, on the right hand side, have a steeper inclination therefore including a larger angle with the bottom line B than the frames in the aft part of the vessel, on theleft hand side, which in? clude a smaller angle with the bottom line B.

At the junctions of the frames with the bottom and side walls of the vessel, they are rounded off, as indicated by the small curved broken lines; r

By my method as above described, I am enabled to produce standard designs for the hullsv of sea-goingvessels resulting in the most favorable contour linesbelow the waterline for the smooth and rapid backward flow of the water when the vessel is in motion along theshor test path, whereby eddies are avoided and friction is reduced to a minimum.

.It should be understood that the invention has been herein shown and described in its broad features only, and that it is not dependent upon theparticular position of the centers of intersection of the ribs, nor on the configuration of said ribs and the relative position thereof, and that modifications are possible, except as otherwise stated in the ap pended -claims.-

To locate the points 0 O for any particular vessel involves a variety of considerations and while no mathematical calculations have as yet been devised for accurately locating these points, same may besubstantially accuratelylocated' on the known basis that for a given speed, the greater the depth and beam of the vessel the nearer said must be located to the line A--Y and farther from the bottom B, these distances being respectively increased and decreased to enable increased speed of the vessel. As a general proposition, it may be stated that for medium speed, me dium draft vessels the point 0 may be 10- cated-below the bottom B a distance approximating the beam of the vessel, and outwardly from the center line X-Y gydistance approximating the depth of the vessel, while the point 0 may be locatedbelow the bottom B and outwardly of the center line XY substantially equal distances approximating the draft or one half the beam of the vesse The approximate proper locations of the points 0 0 thus eing known for a vessel of medium speed and medium draft, it is po'ssible, on the known basis that increasing the beam and draft of the vessel necessltates shifting of said points as aforesaid, to aproxi'mate the proper location of said oints or a vessel of any particular beam, dra and speed. Or, of course, substantiall accurate ositioning of said points may be etermined 4 y experimentation.

I claim 1. The method of determining the inclination of the frames in the fore and aft section v of a ship which consists in generating from a point below the bottom line of the ship radiatmg lines to points on the main diagonals of the vessel, the location of said point depending on the ratio of the beam of the ship to its de th measured from the water-line.

2. he method of determining the inclination of the frames in the fore and aft section of a shi which consists in generating from two di erently located oints below the bottom line of the ship ra iating lines to points on the main diagonals of the vessel, the location of said points depending on the ratio of the beam of the shi to its de th measured from the water-line, the point or determining the inclination of the frames in the aft section being located closer to the bottom line than the point for determining the inclination of the frames in the fore-section.

In testimony whereof I have aflixed my signature.
